This looks a bit different than the original art work and Giovanni says: “While implemented and working here, may not be ready for 3.6, as it is a bit unstable, and the required configuration bits are not there yet“.

Of course screen lock even without PIN will be included in Gnome 360, if not huge surprises happen!

Next work for Giovanni as he says is: “My plan now? First of all, rebasing all this on the new libgdm (which will require some work to get a testing environment). Then I hope to land this right after 3.5.4, and showcase it at the GUADEC“.

Sometimes is better to place your questions on GNOME Community

First I really like the new (un)lock screen, but I think that the “Login as another user” text is to near to the numberblock (its one Gestalt in my eyes, which I thing it should not one).
The second thing is about 3.5.4 the roadmaps (https://live.gnome.org/ThreePointFive/) says its comes today, but I think it comes not today, or? I mean look at 3.5.3. So when it is coming?
